CHURN.

Specification of Letters Patent.

Patented Feb. 4:, 1913.

Application filed September 17, 1912. Serial No. 720,818.

To all whom it may concern:

Be it known that we, VVILLIAM A. FLINT, JAMES B. MCDONALD, and DAVID H.CRABBs, citizens of the United States, residing at Vincennes, in thecounty of Knox and State of Indiana, have invented certain new anduseful Improvements in Churns, of which the following is aspecification.

Our invention relates to improvements in churns, and has particularreference to a concussion vibrating churn in which the churn bodyoscillates between a frame of special construction.

The primary object of the invention is to provide a churn of thischaracter having simple and efficient means for imparting an oscillatorymovement thereto.

Another object of the invention is to provide an improved lockingmechanism for the churn head.

A further object of the invention is to provide an improved constructionof supporting frame from which the churn is suspended and between thevertical sides of which the churn vibrates.

Another object of the invention is to provide an improved constructionof bumper or buffer against which the churn contacts at the end of eachvibration.

A further object of the invention is to improve and simplify theconstruction of churns of this character; to cheapen their cost; and toincrease their usefulness and desirability.

To attain the desired objects, the invention broadly stated, consists ofa supporting structure, a churn suspended therefrom and vibratingbetween the sides thereof, and means for imparting a vibratory movementthereto, the invention further consisting in certain novel features ofconstruction and combinations of parts, substantially as shown.described, and claimed hereinafter, reference now being had to theaccompanying drawing, in which Figure 1 is a side elevation of a churnand churn supporting frame constructed in accordance with and embodyingthe principles of our invention, the position the churn assumes whenvibrated or oscillated being indicated in dotted lines. Fig. 2 is an endview thereof. and Fig. 3 is-a plan view. Fig. 4 is a side elevation of amodified construction of churn wherein an operatiiig handle is connectedto the churn,

and Fig. 5 is a plan view thereof, part of the bail shaped frame beingbroken away.

In the drawings :The numeral 1 designates the base of the churnsupporting structure, from which rise the vertical parallel side members2, formed with the inclined portions 3, terminating in a horizontal bar1, the whole frame being bail shaped in configuration and preferablychanneled, and the side members 2 each having a leaf spring 5 securedthereto at diametrically opposite points by the clamps 6, which springscarry bumpers or buffers 7 of highly resilient material.

The numeral 8 designates the churn, of any desired size, shape, andmaterial, suspended from the horizontal bar 1 of the frame by means ofthe hooks 9 and chains 10, connected with the vertical flanges orextensions 11 of the bail shaped member 12, said churn being confinedbetween the vertical sides of the bail shaped frame and contacting withthe spring actuated buffers carried thereby.

The lid 13 of the churn is provided with a flange fitting over one endof the churn and is held in place preferably by the short wing bolts 14,which pass through openings in the metal plate 5 fastened to the churnhead and let into the same so as to form a level surface at the point ofcontact with the buffer 7 The heads of the bolts fit into slots formedin the flanges or lugs 16 of the plates 17 secured to the body of thechurn. whereby said bolts may be readily disengaged when desired. Thechurn is further provided with a glass covered sight opening 18 toenable the operator to observe the action of the contents of the churn,and a valve 19 of any desired construction is employed for permittingthe escape of gases, while a head or back piece 20 may be fastened tothe end of the churn to prevent the churn body from coming into directcontact with the spring actuated buffers. The means for imparting avibratory or oscillating movement to said churn are eX- tremely simpleand efficient and comprise a bearing plate 21 fitted and secured in thechannel of the channeled bar 4 of the frame, andformed with a journal 22in which is mounted the shaft 23 of the gear wheel 24. having anoperating handle 25 and meshing with the pinion 26. whoseshaft 27 isjournaled in the journal 28 of said bearing plate 21 and carries uponits other end a wheel 29 formed with a stud 30 en gaging a slide plate3l adapted to work in an elongated slot 32 formed in the outer end of areciprocating lever 33, the inner end of which is connected to a bracket3%, the lower end of which is connected to a vertically disposedoscillating member 35, which has connection with the bail shaped member12 of the churn. From this construction, it will be seen that rotationof gear wheel 24: will cause pinion 26 to rotate, thus rotating wheel29, which through its novel connection with the lever '33 will causesaid lever to reciprocate and through its coni'iection 34 and 35 withthe bail, shaped member 12 of the churn, will oscillate said churnbetween the vertical parallel sides 2 of the supporting structure, asbest shown in Fig. 1, the springs in the buffers serving to preserve thelife of the rubber.

In the modification shown in Figs. l and 5, the supporting frame andchurn are similar to that shown in Figs. 1, 2 and 3,

but instead of the cogs and lever therein illustrated, we employ anoperating handle 100 connected directly to the bail shaped member 12 ofthe churn. This construction provides simple and easily constructedmeans for oscillating the churn.

From the foregoing description, taken in connection with theaccompanying drawings, the construction and operation of our improvedchurn will be readily seen and understood, and it will be apparent toall that the means herein described will prove simple, inexpensive, andhi hly efficient and reliable for aoco'mplishingthe objects heretoforestated. i

It will of course be understood that we do not limit ourselves to thedetailed con struction herein shown and described, but reserve the rightto make such changes and modifications as come within'the spirit andscope of the invention, as defined in the ap' pended claims.
